Price Range
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
Series
Many brands group their products into series or lines of products to help customers know the level of quality (good, better, best for example). You can filter by series and the brand using our guided browsing.
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.
Top-Mount Depth (Mounting Depth)
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
  Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.

    FAQ Frequently asked questions in 6.5" & Small Car Subwoofers

    6.5" & Small Car Subwoofers Frequently Asked Questions (FAQ)
    Yes, 6.5"" and small car subwoofers can deliver good bass, but their performance may differ from larger subwoofers. While they may not produce the same deep and booming bass as larger counterparts, they are well-suited for adding clarity and punch to the lower frequencies. These subwoofers are ideal for music genres that emphasize mid-bass and offer a more balanced sound. Additionally, small subwoofers are perfect for vehicles with limited space, as they can be installed in smaller enclosures that do not compromise trunk or cargo space. To optimize their performance, consider pairing them with a compatible amplifier that provides the right amount of power and a suitable enclosure that complements their size and power handling capabilities. When properly installed and matched with the right components, 6.5"" and small car subwoofers can significantly enhance your car audio system with enjoyable bass response.
    Yes, you can install 6.5"" and small car subwoofers in a factory audio system, but it may require additional components and modifications for optimal performance. Most factory audio systems lack the power and low-frequency output necessary to produce impactful bass, which is where subwoofers excel. To integrate the subwoofers with a factory system, you'll need a compatible amplifier to provide sufficient power to the subwoofers. Additionally, a line output converter (LOC) may be necessary to connect the amplifier to the factory head unit. It's essential to adjust the amplifier settings and tune the audio system correctly to ensure the subwoofers complement the factory speakers without overpowering them. Professional installation is recommended to ensure a seamless integration and to prevent any potential issues with the factory system. When installed correctly, 6.5"" and small car subwoofers can significantly improve the bass response and overall audio quality of your factory audio system.
    The type of enclosure that is best for 6.5"" and small car subwoofers depends on your desired bass response and the available space in your vehicle. The two common types of enclosures are sealed and ported (vented) enclosures. A sealed enclosure provides accurate and tight bass, making it suitable for music genres that demand precision, such as rock and jazz. On the other hand, a ported enclosure enhances low-end output, delivering a more resonant and boomy bass that complements genres like hip-hop and electronic music. However, ported enclosures require more space compared to sealed enclosures. If you have limited space in your vehicle's trunk or cargo area, a sealed enclosure may be a better choice to maximize bass performance without sacrificing space. Ultimately, the best enclosure type for your 6.5"" and small car subwoofers will depend on your musical preferences and the available space in your vehicle.
    Yes, you can use 6.5"" and small car subwoofers in a compact car or truck, and they are an excellent choice for vehicles with limited space. Their smaller size allows for more flexible installation options, making them suitable for compact cars, trucks, and even motorcycles. Installing small subwoofers in compact vehicles allows you to enjoy improved bass without compromising passenger and cargo space. To optimize their performance in smaller vehicles, consider using a compact and sealed enclosure that fits well in the available space. Additionally, matching the subwoofers with a suitable amplifier and tuning the audio system correctly can further enhance their performance and ensure they complement the rest of the speakers in your car. Whether you have a compact car or a small truck, 6.5"" and small car subwoofers can significantly enhance your audio experience with tight and impactful bass.
    The power requirements for 6.5"" and small car subwoofers depend on their power handling capabilities and your desired bass output. Smaller subwoofers generally have lower power handling compared to larger ones. It's essential to match the subwoofers' power handling rating with an amplifier that can deliver the appropriate amount of power. For example, if the subwoofers have a power handling rating of 200 watts RMS each, the amplifier should ideally provide around 200 watts RMS at the same impedance to avoid overpowering or underpowering the subwoofers. Underpowering can lead to distorted sound and possible damage to the subwoofers, while overpowering can cause overheating and potential failure. Consider the subwoofers' sensitivity rating as well; a higher sensitivity means the subwoofers can produce more sound with less power. By ensuring proper power matching, you can optimize the subwoofers' performance and enjoy clean, powerful bass in your car audio system.
